Leigh,
The Orbeon implementation only supports one label, help, hint, or
alert for a given control.
I think there was discussion in the group at some point to support
multiple alert messages, possibly tying them to individual binds. I
can see how that could make sense. That would definitely fall in the
"future feature" category.
